APX810S-31SA-7 from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground. |
| 2 | RESET | output | Active-high push-pull reset output (APX810S) that is asserted when VCC falls below the reset threshold and held for at least 240ms (typ. 240ms) after VCC rises above it, valid down to VCC = 1V. |
| 3 | VCC | power_in | Operating voltage input, 1.0V to 5.5V recommended, absolute maximum 6.0V. |
